Phospholipid head function
WebPhospholipid: Amphipathic lipid made of glycerol, two fatty acid tails, and a phosphate group: Phospholipid bilayer: A biological membrane involving two layers of phospholipids with their tails pointing inward: Semipermeable membrane: Membrane that allows certain substances to pass through WebThe different classes of PLases have important and diverse functions that are fundamental to life. The removal of acyl chains or phospholipid head group by PLases and the subsequent remodelling of these hydrolytic products to make new lipids have important roles in lipid signalling, membrane trafficking and nutrient digestion.
